액정(liquid crystal)은 고체와 액체의 중간 특성을 갖는 물질로서, 전압과 온도의 변화에 따라 빛을 투과 또는 차단시키는 성질이 있다. LCD (liquid crystal) has the property of transmitting or blocking the light in response to changes in voltage and temperature of a material having intermediate properties of a solid and a liquid.따라서, 특정 부분의인가전압과 온도를 적절히 조절함으로써 명암의 상태를 제어하여 원하는 형상을 표시할 수 있다. Therefore, it is possible in certain parts is by properly controlling the voltage and temperature to control the state of the contrast can display a desired shape.액정표시장치는 이와 같은 성질을 이용한 표시소자로서, 소비전력이 다른 디바이스에 비해 매우 작고, 초소형에서 대형까지 다양한 크기의 생산이 가능하며, 표시 패턴을 다양화할 수 있다는 장점이 있어 표시장치 분야에서 중요한 위치를 차지하고 있다. The liquid crystal display device In a display device using the same nature, the power consumption is very small compared to other device, from miniature to large it can be of varying sizes produced and it is an advantage that can vary the display pattern key in the display field It occupies a position.

이와 같은 모드의 기본 원리는 액정의 굴절율 이방성과 액정 평균방향과 편 광판 방향 사이의 각도 관계에 의하여 광을 조절하는 것이다. The basic principle in the same mode is to adjust the light by the angular relationship between the refractive index anisotropy of the liquid crystal and the liquid crystal orientation as the single average gwangpan direction.이러한 모드의 정면에서의 광투과율은 다음과 같은 수식으로 표현될 수 있다. The light transmittance at the front of these modes can be expressed by the following formula.

여기서, θ는 입사광쪽의 편광판 투과축과 액정방향 사이 각도, d는 셀갭, Here, θ is the angle between the transmission axis of the polarizing plate and the liquid crystal orientation of the incident light side, d is the cell gap,

)가 다르게 변함에 따라 도 3의 특성 그래프에서 알 수 있듯이, 그레이(gray)에서의 칼라(color) 특성 차이가 큼을 알 수 있다. ) A As can be seen from the characteristic graph of FIG. 3 in accordance with the change differently, the color (color) properties of the difference in gray (gray) can be seen is great.

한편, 이상에서와 같은 복굴절 모드를 응용한 것중의 하나로 LFI(lateral field induced)-VA 모드가 있다. On the other hand, the one LFI (lateral field induced) -VA mode of the things an application of birefringent mode as shown above.이 모드는 도 5a 및 도 5b에 도시된 바와 같이 상부판의 공통전극과 하부판의 패턴화된 전극 구조를 갖는 것으로서, 상부판은 슬릿 방향으로 러빙한 구성을 갖는다. This mode as having a patterned electrode structure of a common electrode of the upper plate and the lower plate as illustrated in Figures 5a and 5b, the upper plate has a configuration in which the rubbing direction with a slit.도 5a 및 도 5b에서 참조번호 501은 ITO 전극, 502는 유리기판, 503은 편광판, 504는 액정을 각각 나타낸다. Figures 5a and 5b in the reference number 501 is an ITO electrode, 502 denotes a glass substrate, 503 is a polarization plate, 504 denotes a liquid crystal, respectively.

이 모드에서는 전압이 인가되지 않은 상태에서의 액정의 배향 분포가 거의 수직이므로, 광이 통과하지 못한다. In this mode, because it is almost the liquid crystal aligning distribution of the non-energized state the vertical, the light does not pass.전압인가 시 하부판의 전극 구조에 의한 횡전계와 수직전계의 복합 작용에 의해 멀티-도메인(multi-domain) 구조를 갖는다. When voltage is applied by the composite action of the lateral electric field and a vertical electric field due to the electrode structure of the lower plate multi-domain have a (multi-domain) structure.이 구조의 가장 간단한 모식도는 도 5c에 도시된 바와 같다. The simplest is a schematic view of the structure is shown in Figure 5c.이 구조에서 전압 인가 시 하부판 전극과 슬릿 경계부의 액정 방향은 약간의 비틀린 구조를 가지게 되며, 전극의 좌,우에 위치한 도메인이 서로 90도 시야각 방향이 다른 ECB 특성을 보인다. Crystal direction of the lower plate electrode and the slit boundary portion when a voltage is applied in the structure is to have a small torsion structure, the left and Yiwu domain in the 90 degree viewing angle direction with the electrode shows different characteristics ECB.파장별 투과 특성을 보면, 도 6에 도시된 바와 같이, 전압에 따른 투과 특성이 파장별로 차이가 남을 알 수 있다. When the wavelength-specific transmission characteristics, a difference can be seen by the others, the transmission characteristic of the voltage wave, as shown in Fig.이는 곧 그레이별 칼라 특성 변화의 문제가 있음을 의미한다. This means that there is a problem of the gray-specific color characteristics.

Reference to the accompanying drawings will be described in detail the embodiments of the invention.

도 7a 및 도 7b를 참조하면, 본 발명에 따른 칼라 액정표시장치의 제1실시예는 LFI-VA 모드의 액정표시장치로서, 전압 인가에 따라 전계를 형성하는 양측 전극 중의 일측 전극으로서의 공통전극(701)과, 각 색상에 따른 특정 파장의 광만을 통과시키는 칼라필터(702)와, 전계 형성을 위한 양측 전극의 형성을 위한 베이스를 마련해 주는 유리기판(703) 및 광을 선택적으로 투과 혹은 차단시키는 편광판(704)이 순차적으로 적층 형성되는 상판부와, 그 상판부와 소정 간격 이격되어 마련되며 또 다른 편광판(704') 및 유리기판(703')과 그 유리기판(703') 위에 적, 녹, 청 각 색상별에 대응하여 형성되는 화소전극(705)을 갖는 하판부와, 상기 상판부와 하판부 사이의 공간에 채워지는 액정(706)을 구비한다. When FIG. 7a and FIG. 7b, the first embodiment has a common electrode serving as one electrode of a liquid crystal display device as in the LFI-VA mode, both electrodes to form an electric field in accordance with the voltage applied to the color liquid crystal display device according to the present invention ( 701) and, with a color filter 702 that transmits only light of a specific wavelength for each color, that selectively transmits or blocks the glass substrate 703 and the light that provided the base for the formation of both electrodes for electric field formation polarizing plate 704 and the top plate is formed are sequentially stacked, is provided spaced from the upper plate with a predetermined interval other polarizing plate (704 ') and the glass substrate (703') and the glass substrate (703 ') on the red, green, and blue It is provided with a liquid crystal 706 filled in the space between the lower plate and the upper plate and the lower plate having a pixel electrode 705 is formed corresponding to each color-coded.

여기서, 특히 상기 칼라필터(702)의 각 색상별에 대응하여 각각 마련되는 상기 화소전극(705)은 본 발명의 특징에 따라 각 색상별로 그 폭이 각각 다르게 구성되고, 그 화소내의 전극들 간의 슬릿폭도 각각 다르게 구성된다. Here, in particular, the pixel electrodes 705 which are respectively provided corresponding to each color of the color filter 702 and the width configured differently for each color according to the teachings of the present invention, the slit between the electrode within the pixel It consists of the width different respectively.

이상과 같은 구성을 갖는 본 발명에 따른 칼라 액정표시장치의 제1실시예에 있어서, 전극폭이 슬릿폭에 비해 상대적으로 커질수록 도 8에 도시된 바와 같이, 광투과율이 임계 전압(threshold voltage)값 이상에서 빠르게 증가하다 포화됨을 알 수 있다. In the first embodiment of the color liquid crystal display device according to the present invention having the above construction, as the relative increase in electrode width compared to the slit width as shown in Figure 8, the light transmittance of the threshold voltage (threshold voltage) it is rapidly increasing in value, it can be seen that over saturated.이와 같은 특성을 고려해 볼 때, 청색(B) 화소의 투과율이 녹색(G)이나 적색(R)에 비해 동일한 크기의 전압에서 커져야 함을 알 수 있는 바, 상기 제1실시예의 전극 구조는 바로 그와 같은 점을 고려하여 설계된 것이다.
